What are the alternatives to the fujifilm gf 30mm f 5 6 t s?
The Fujifilm GF 30mm f/5.6 T/S is a wide tilt-shift lens for architecture and landscape. I don't have another wide tilt-shift lens on the site to suggest as a direct alternative.
The closest option I list is the Fujifilm GF 110mm f/5.6 T/S Macro. It uses the same Fujifilm G mount and also has tilt-shift, but it's a very different tool. It's a manual-focus macro that focuses to half life size, so it suits close-up work rather than wide views of buildings.
If you're mainly after sweeping landscapes, the landscape guide covers the rest of the kit that will help more than a different lens would.
